Having thus described the parts of my .invention I will now explain the construction and applying same to the vault door.

The upper auxiliary locking bolt is a straight bar with a hole in the upper end thereof and the trigger in the lower end thereof. The sleeve 5 in which it rests is secured to the flange I) by bolts 60. The lower end of the sleeve being concaved to fit the periphery of the cross bolt C.

The lower auxiliary locking bolt l has stem 61 projecting upward therefrom with a hole in the upper end thereof. A spring 8 is placed over the stem 61 and then the stem is placed through the hole in the up-' per endof the sleeve 5' in which the auxiliary locking bolt 4 operates. The sleeve 5 is secured to the flange D by bolts 63. Tl e lower end of the sleeve 5' is concaved to fit the periphery of the cross bolt C.

A catch can be placed in the end of each of the auxiliary locking bolts if so desired. In describing the construction of the auxiliary locking bolt with the emergency trigger therein I will refer to the bolt 1.

In the lower end of the auxiliary bolt I drill two holes partly through the bolt. One hole 12 runs parallel with the length of the bolt and the other hole 18 drilled horizontal thereof. Through the wall of the bolt and in the end of the hole 18 I cut the slot 19. I now place in the hole 12 the spring 12 and the locking pin 13 and push them in past the hole 13. Now take the trigger 17 placing the tongue 20 through the slot 19. Now take the spring 21 and place it at one side of the trigger 17 so it will not interfere with the operation of the pin 13 in dropping back of the trigger when the trigger is thrown outward or in the emergency locked position. Now I take the screw plug 1 c and place it in the hole 12 and the other plug 22 and place it in the hole 18 thus holding the movable parts within the bolt. The trigger is held within the bolt by the wall of the sleeve and the hole in the cross bolt in which the auxiliary bolt rests and operates.

The main operating lever which is a bell crank lever 1 has a slot 23 in the end of the short arm and a. hole 24 in the long arm thereof and a hole 25 located at the fulcrum bend thereof, for pivotally connecting the bell crank to the cover H of the casing E.

The connecting rods 3 and 29 and the link 2 are made in many shapes and lengths so as to fit the required placing of the auxiliary locking bolt on the vault door.

In applying the bell crank lever 1 to the permutation look, I remove the cover H and cut a rectangle hole 26 therein. Now I remove the lock bolt F and drill and thread a hole 27 therein in which I place the pin 28. N ow replace the bolt F in the casing and then place on the cover H. Now take my bell crank lever 1 and place the slot 23 therein over the pin 28 and then take the set screw 30 place it through the hole 25 and through the hole in the cover II and then into the hole in the lug K in the casing it. The set screw 30 has a shoulder thereon which prevents the screw being turned too 7 far into the hole in the lug K and also prevents the bell crank lever from being too tightly drawn to the cover H to prevent the free movement thereof.

On the top of the casing E I place a staff 31 to which I attach one end of the spring 32 to the upper end thereof and the other end I attach to the bell crank lever l. in the hole This spring draws the bell crank upward upon the turning of the handle L to the downward position as shown in the drawings.

After the location on the door where the auxiliary bolts are to be placed has been decided, I drill a hole 7 through as many of the cross bolts C as there are auxiliary bolts to be placed on the door. As shown on the drawings I have placed two on the door for illustration, but as many may be used as desired.

After the holes 7 and 7' have been drilled in the cross bolts C and C, I drill other holes in the flange D of the door and secure the casing of the auxiliary bolts thereto by screws 60 and 63. After the auxiliary bolts have been so placed, I take the link 2 and pivotally attach one end thereof to the hole 2 1 in the bell crank lever 1 and the other end thereof I attach to one end of the lever 3. Now I drill a hole at any desired place on the door wall and tap same to receive a screw 34. Now I take the screw 3% and place it through the center hole in the lifting lever 3 and then secure the screw within the hole, thus pivotally connecting the lifting lever 3 to the wall of the vault door. I now take the other end of the lifting lever 3 and place it over the end of the pivot pin 37 on the auxiliary locking bolt e thus allowing the slot 58 in the end of the lever 3 to move over said pivot pin, said pivot pin being soldered to the auxiliary locking bolt 4. Now I take the spring 35 and secure one end thereof to the lifting lever 3 and the other end to a screw in said vault door.

Where there is more than one auxiliary bolt used on the vault door, I use a connecting rod 29 and pi votally connect the upper end thereof to the arm 37 of the auxiliary locking bolt Al and the lower end thereof I pivotally connect to the eye in the end of the lower auxiliary bolt.

With my invention so applied to the vault door the operation will be as follows.

The movement of the bolt F and the auxiliary bolts 4 and is effected by the direct action of a series of rotating tumblers of the permutation lurk; The dog G pivoted at one end to the bolt l carries at the lesseesother end pio e ehg arm" svgwhieh,

I f Theseconneetions are of very weak 1 al and will be broken with very little lVhen the auxiliary bolts have passed through the cross bolts as shown in Fig. 7, the tongue 20 of the trigger 17 is forced out of the slot 19 by the spring 21 thus allowing the locking pin to drop down behind the trigger into the lower end of the hole 12, thus locking the trigger so it is impossible to push it back into the hole 18 until the pin 13 has been replaced.

To open the door after the auxiliary locking bolts have been tiirown into the emergency position, the following steps a ne taken When the auxiliary bolts are placed on the door a measurement of their location is taken and placed away for record. In opening the door this record must be used to get the exact location of the auxiliary bolts. At this location a hole is made into the door to allow the necessary tools to be placed therein to remove the screw in the bottom of the au iliary locking bolt. After the screw 14 has been removed the pin 13 will drop out to the floor of the vault. After the pin 13 is out of the way the tongue 20 can be put back into the slot 19 by the use of a rod or screw driver being placed through the hole in the vault door. then the auxiliary locking bolt can be moved up through the hole in the cross bolt thus allowing, the cross bolts to be moved back to unlock the vault door.

After the door has been opened the broken parts are all removed and new parts placet therein. The auxiliary bolts are left in the same position or changed to some other lo cation on the door.
